MARK W. MARSDEN, OF PHILADELPHIA, PENNSYLVANIA.

SYSTEM FOR COOLING AND DISPENSING BEVERAGES.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed June 23, 1903. Serial No. 503,901.

It all whom it may concern Be it known that I, MARK W. MARsDEN, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful System for Cooling and DispensingBeverages, of which the following 1s a s ecification.

This invention relates to systems for cooling and dispensing beer, ale, porter, and other beverages on draft.

One of the principal objects isto provide an installation that shall absolutely sanitary.

Another object is to provide an installation that shall be simple in construction and mode of operation and which may be easily set up in the place of old systems Without dismantling the bar.

Another object is to provide for cooling beverages with but a fraction of the quantity of ice heretofore required.

Another object is to provide.an air circulating and cooling system wherein the beverage connections are substantially enveloped byair cooled passages and wherein some of the air is used for forcing purposes.

'There are further objects whereof some are obvious and others will be referred to with more particularity in the course of the detailed description.

The nature, characteristic features and scope of the invention will be more readily understood from the following description taken in connection with the accompanying drawings, forming a part hereof, wherein- Figure 1, is a View principally in perspective showing the general arrangement of the units. Fig. 2, is a sectional View through the bar or ice box. Fig. 3, is a sectional view of the lower cylinder showing accessories and contents thereof. Fig. 4, is a sectional view .of the beer rod and its connections; and

Fig. 5, is a sectional fragmentary view of the beer rod. v

Referring to the drawings 1, is a bar of usual construction whereof the cabinet or ice-box 2,is equipped with air containing tanks or cylinders 3, whereof the number may vary according to the size of the icebox or other features of the installation. For convenience and also because it is desirable to have them immersed in the ice water that accumulates in the ice-box they are laid in the bottom'thereof. Said tanks or cylinders are connected in series or intercommunicate, as at 4, and one of them has a valved inlet 5, for air of the desired temperature and compression, the air compressor not being shown. The air circulating through the battery of tanks has its temperature further reduced and passesthrough a reduction valve 6, into a jacket or casing 7, that incloses'a plurality of beverage conduits or passages 8. The jacket or casing 7, extends down to the cellar or wine room or to a point con'tiguous the cask or barrel containing the beverage and is connected by a suitable coupling 9, with a double tank or' distributing cylinder 10, into which the air discharges. Said cylinder is equipped with a number of couplings or openings 11, one for each beverage conduit or connection 8, and the latter passes through the respective coupling and a clamp 12, connects it to the valve 13, of a beer rod 14. The latter is almost entirely inclosed by a acket or casing 15, and the space between the two constitutes an air chamber 16,

that is separated by plates or baflies 17 Fig. 5, with openings 18, near the bottom so that the air passes down one side and up the other.

19, indicates a bung, which is carried by the rod and which coeperates in the Well known manner with the bushing 20, on the barrel or cask to secure a tight joint. There is an annular air space or chamber 21, in the bung, which air space communicates with the air chamber 16, of the rod by a vent 22, and at 23, there is some clearance between the bung and the jacket 15, to permit air to pass into the barrel or cask for forcing purposes.

The outer ends of the couplings 11, are stopped by disks or washers 24, so that a consequent air space 25, is provided which has a vent 26, whereby communication may be had between the air space 25, and the air space 22, in thebung, by means of a valved connection 27 The air jacket or casing 15, on the beer rod has a vent or outlet 28, and a valved connection 29, connects it with anair exhaust cylmder 30, that is equipped and 34, 35, respectively, so that flushing may m eeasre be resorted to from time to time as may be necessary to keep the system clean and sanitary.

The connection in the ice-box or cabinet between the beverage conduits or passages 8, and the draw cocks or faucets 36, maybe straight connections as at 37, or coils, as at 38. Both types of connections are shown in Fig. l.

It is manifest from the foregoing description that with a minimum quantity of ice and by the use of air at an appropriate pressure, 1 am enabled to cool and dispense beer, ale, porter, and other beverages more economically than has heretofore been accomplished and most important of all under perfect sanitary conditions.

Having described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination of a draw-box adapted for ice, a tank therein for containing air under pressure, a beer keg, a beer rod penetrating the same and having a surrounding air acket equipped with an exhaust, a bung having an air chamber communicating with said jacket and having a separate outlet for supplying air to the keg for forcing purposes, and a connection intermediate the bung and air pressure tank including means for regulating the pressure, substantially as described;

2. In combination, a beer keg, a beer rod penetrating the same and having an aircooled jacket, a bung carried by the rod and having an air chamber communicating with both the jacket and the keg, a draw-box and its accessories, a draft connection intermediate the rod and box, an air-cooled jacket or casing substantially inclosing said connection and communicating with said air chamber, means for directing cold air at an appropriate pressure into said casing, and suitable exhaust connections communicating with the rod acket, substantially as described.

3. In combination, a beer keg, a beer rod holder and air chamber, and a receiver adapted and arranged to take air from the air acket and equipped with a relief valve, substantially as described.

i. The combination of a cold air conduit extending from the bar to a point'contiguous the beer keg, draft connections traversing said conduit, a beer rod terminating said connections ahd having an air-cooled chan1- her or jacket, and a bung carried by the rod and having an air chamber adapted and arranged to take air from said conduit and supply some to the keg for forcing purposes and some to the air jacket, said jacket having a suitable exhaust so as to maintain a substantially constant circulation of cold air, substantially as described.

5. The combination of a draw-box adapted for ice, a tank therein for containing air under pressure, a second or distributing tank, means for intermittently discharging cold air from the first tank into the second,

a beer keg, a beer rod penetrating the same, and having an air.jacket equippedwith an inlet and an outlet, a bung having an air chamber that has ,an insulated connection with the second tank and supplies air to the keg for forcing purposes and air to the jacket for cooling purposes, automatic exhaust mechanism associated with the out-let of the jacket, and an insulated draft connection extending from the rod to the drawbox, substantially as described.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
